Circa 1755 On 490 Acres! Maryland’s Most Expensive Old House Listing!

19700 Mulberry Fields Rd, Leonardtown, MD 20650

Every once in a long while, a property comes along that isn’t just a home, but a living, breathing part of history. Mulberry Fields is exactly that. Built in 1755, this estate has stood for over 270 years. It has watched the birth of the United States and survived through centuries of change. When you drive down the long, cedar-lined driveway, the modern world just disappears.

This is the only Georgian manor house left in St. Mary’s County. For someone who truly loves old houses, this is the ultimate prize. It represents a time when homes were built by hand with incredible skill and meant to stand forever. It’s not just a house; it’s a landmark.

One of the most beautiful parts of this estate is the “Avenue Field.” From the front of the house, there is a mile-long stretch of land lined with trees that leads your eye all the way down to the Potomac River. It creates a panoramic view that most people only see in movies.

Imagine standing on your porch and looking down a perfect grassy hill to see a white sandy riverbank a mile away. It is one of the most peaceful and grand views in the entire country. Having a full mile of your own private shoreline on the Potomac is a luxury that almost no one else can claim.

The interior of this mansion is a dream for lovers of 18th-century architecture. The main hall and the two front rooms are filled with rectangular raised wood panels that go all the way to the ceiling. This is very rare! It is one of the most complete examples of paneled 18th-century woodwork in all of Maryland.

The taste inside is simple and elegant. You will find original moldings, heavy doors, and hand-carved mantels that have been preserved for hundreds of years. While it feels like a museum, it is also a comfortable home. The owners have already added modern heating and air conditioning, so you can enjoy the history without being cold in the winter!

The manor house is surrounded by smaller historic buildings called “dependencies.” These brick buildings were used as a kitchen and a weaving house in the past. They are placed perfectly to form a beautiful courtyard. This layout makes the property feel like a small, busy village from the 1700s.

The “Kitchen” has already been turned into a cozy guest cottage. The “Weaving House” still has its original wood walls and hardware. Walking through these buildings is like stepping into a time machine. You can see how people lived and worked hundreds of years ago.

Beyond the main houses, the property is filled with historic structures. There is a Dairy, a Meat House, a Carriage House, and even an Art Studio. If you love farming or animals, you will find a Horse and Cattle Barn, a Tobacco Barn, and even a remodeled Sheep Barn.

There is also a Garage and Tool Shed, plus several equipment barns. Whether you want to collect vintage cars, start a large-scale farm, or create an art retreat, the space is already here. You even have an old dwelling that is just waiting for a renovation to become another rental unit.

Owning a 500-acre estate is a big job, but Mulberry Fields helps pay for itself. Right now, there are six rental units on the property that bring in $70,000 every year. This includes three units in the old Sheep Barn and a separate farmhouse.

There is also income from leasing the fields for farming and even a signal used by the Navy on the river. If you wanted to, you could renovate more of the buildings to create a total of twelve rental units. It’s a great way to maintain a historic property while making it a smart business investment.

With nearly 500 acres, you have your own private world. About 300 acres of the land is deep forest, perfect for hiking, bird watching, or just finding some quiet time in nature. The other 100 acres are fertile fields used for farming.

The land is protected by conservation easements. This means the beauty of the forest and the farm will stay just as they are for generations to come. You are buying a guarantee that your view will never be ruined by a busy shopping mall or a crowded housing development.

While the house is beautiful as it is, the current owners have already done the hard work of planning for the future. They have architectural plans approved by the Historic Trust to enlarge the kitchen and bathrooms and even add a whole new wing to the house.

This is perfect because it allows you to bring the home into the modern age while respecting its history. You can have a giant, chef-quality kitchen and luxury bathrooms while keeping the 1755 charm intact. The plans are ready and waiting for the next owner to start.

Even though it feels like a world of its own, Mulberry Fields is very close to local towns. Leonardtown, Solomon’s Island, and Lexington Park are just a short drive away. You can find local wineries, antique shops, and great seafood restaurants nearby.

If you travel for work or fun, you are only about an hour and fifteen minutes from Washington D.C. and major airports. There is even a private jet airport nearby. You can live in complete historic privacy and still be at a meeting in the capital or at the airport in no time.

Buying Mulberry Fields isn’t just about buying real estate; it’s about becoming a guardian of American heritage. This home was added to the National Registry of Historic Places in 1973 for a reason—there is nothing else like it.

It is a place where you can host grand parties, run a working farm, and wake up every day to a view of the Potomac that hasn’t changed much since the 1700s. It is a home for someone who wants to leave a lasting legacy.

Let’s talk one more time about that riverfront. A mile of white sand on the Potomac is truly special. You can take long walks, search for fossils and shells, or just sit and watch the boats go by. It’s a private beach that belongs only to you.

Having water access like this is incredibly rare for a historic manor. Usually, you get the house or the water—rarely do you get both with 500 acres in between. It is the crown jewel of this property and the reason why Mulberry Fields is a once-in-a-lifetime opportunity.

Mulberry Fields is a masterpiece. Between the 1755 Georgian architecture, the huge income potential, and the massive amount of land, it is one of the most significant properties on the East Coast. It is waiting for someone who loves the smell of old wood, the sight of a river at dawn, and the feeling of history under their feet.
